TRAP-MEST.

Application led May 21, 1913.

To all whom t may concern:

Be it known that I, Enwnriv O. BEARING- 'ro2 or" Rochester, in thecounty of Monroe and State of New York, have invented a new and usefulimprovement in Trap-Nests, which improvement is fully set forth in theJfollowing specification and shown in the accompanying drawings. v

illy present invention relates to trap nests and has t'or an object toprovide an iniproved means by which the entrance door will be closed assoon as the hen occupies the nest, and its escape thereby preventeduntil released by an attendant.

ln poultry yards where select stock is kept it is desirable that theeggs laid by each hen be properly recorded and it is another object ofthis invention to provide means whereby the laid by a, hen occupying anest will operate a. signal calling the notice of an attendant in orderthat the hen may be released and the egg properly credited.

To these and other enes the invention consists in certain parts andcombinations of parts all oie which will be hereinafter described, thenovel features being pointed out in the appended claims.

ln the drawings: Figure 'l is a front elevation of' a nest constructedin accordance? with my invention, showing the door closed; Fig. 2 is avertical sectional view on the line of Fig. l showing the door in openposition; Fig. 3 is a similar view with the door closed; Fig. et is avertical sectional view on the line 4l-fl of Fig. 2; and Fig. 5 is adetail sectional view on the line 5`5 of rig. i.

The nest embodies a casing 1 preferably formed of the side walls 2 andback 3 of sheet metal and united at their meeting edges by the angleirons 4: which project beyond the bottom of the casing to form rearsupporting legs therefor. The front of the casing is left open and theangle bars 5 secured to the front edges of the side walls 2 andconstituting the front legs are connected at their upper ends by a crossbar 6 and beneath the casing by the cross bars 7. A top 8, provided witha suitable Ventilating aperture covered vwith wire netting 9, is securedin place by the depending flanges 10. The door or closure 11, alsoprovided with a. ventilating opening similarly covered with netting, ismovable vertically7 in guides l2 on the front angles 5 and, when open,occu- Speccaton of Letters Patent.

pies the position shown in Fig. 2, with its l upper edge about even withthe lower edge ot the casing. Carried by and depending from the sidesare guides 18 in which slide blocks le on a frame l5 vertically movablein the casing. A cloth or other suitable flexible material 1G extendsacross the frame and constitutes the nest proper, a slight amount ofslack egg laid therein will gravitate toward the center where it willfall through an aperture 17 therein and be conducted by a chute 1S ofsimilar flexible material without danger of breakage to a paddedrepository or pocket 19 carried on a hanger 20 depending yfrom the framelo. The pocket'l9 is open at the top and, inasmuch as it is locatedbeneath the lower edge of the casing, an egg contained therein is easyof access to the attendant.

The nest 16 and door 1l are operatively connected so that they normallycounterbalance each other, but, when the nest is occupied, itwill falland raise the door as shown y in Figs. l and 3 to prevent the escape ofthe hen. Fivoted at 2Oa above the guide 13 on the sides 2 are'levers 21connected at their forward ends by links 22 to the door, their rear endsbeing engaged by pins 23 extending laterally from plates 2e at theextremities of levers 25 pivoted at 2G to the casing. The nest frame 16is provided with upwardly extending shields 27 which eifectually coverthe levers, and afford a convenient means of attaching links 28 whichare connected theretov at 29 and to the levers 25 intermediate of theirends at the point 30. lt will be seen from an inspection of Fig. 2 thatdownward motion of the nest causes the levers 25 to bear downwardly onthe rear being allowed so that an ends of levers 2l and on account ofthe rela-` tive locations of the pivots, an amplified movement istransmitted to the door 11. l It will be seen that the top of the dooris about the same level in Fig. 2 as the nest frame and in order tobridge the gap between the two so that there will be no danger to thehens feet while entering, l pro-y vide a member or plate 3l hinged at 32on a bar 34 extending across between the angle irons 5 and in front ofthe door. l/Vhen the door rises, the plate is deflected upwardly andassumes the position shown in F ig. 3 riding against the front face ofthe door. The plate 3l is notched at 36 to receive a linger piece 37projecting forwardly from the upper edge of the door. lVhen theattendant presses down on the linger piece to open the door, the plate3l 'falls by gravity as soon as the door reaches its lowermost position.ln case it is desired 'for any reason to prevent the operation ot thedoor, a gravity latch 38 may be swung down over the plate 3l as shown indotted lines in l.

In order to call to the notice ot' the attendant, the fact that an egghas been laid, a spring arm 89 is located at the bottom ot the chute 18and adapted to be dellected by the .veight of an egg into contact with aterminal Ll0 of an annunciator circuit Ll operated from a source ofelectrical energy 462. ln order for the egg to arrive at the pocket 19it must pass by and depress the arm 39 to close the circuit and operatethe annnnciator 43. The interior lining 18a forming a portion of thechute covers the Contact 89 to prevent injury to the eggs.

Of course Where a plurality ot nests are employed each has its separateannnnciator, thereby obviating the necessity ot a perscnal inspectionot' each nest to see it it is occupied and it any egg has been laid.

`What l claim as my invention and desire to secure by Letters Patent is:

l. The combination with a casing having an opening at one side, avertically movable door tor said opening, and a nest mounted to movevertically in the casing, of a lever pivoted to the casing and connectedat one end to the door, and a second lever pivoted to the casing,slidably engaging the lirst lever and actuated by the nest.

2. The combination with a casing having an opening at one side, avertically movable door for said opening,.and a nest mounted to movevertically in the casing, oi' a lever pivoted at one end to the casingand conn ected intermediate oi its ends to the nest, a second leverpivoted intermediate ot its ends to the casing, the tree end of the'first named lever slidably engaging one end ot the second lever and theopposite end ol' the second lever beingq connected to the door.

3. The combination with a casing having an opening in one side, avertically movable door movable upwardly to close the opening, and anest movably mounted Within the casing, oli two pairs ot' levers mountedWithin the casing above the nest, the pairs being arranged on oppositesides of the nest and the lower member of each pair being connected onone side of its pivot to the door and slidably engaged on the other sideof its pivot by one end of the upper lever, and the upper lever beingconnected with the nest at a. point between said engaging end and thepivot of said upper lever.

Ll. rl he combination with a casing having an opening therein, avertically movable door adapted to move upwardly to close the opening,and a movably mounted nest in the casing connected to the door forraising the latter, of a hinged member adapted to project over the topof' the door When the latter is open into proximity to the nest, and tobe deflected to one side ot the door when the latter is elevated, and alatch for engaging the hinged member to prevent its dellection.
